one side of the orifice as the rod is moved in and out by' the throttle or suction motor, orboth.

According to the present invention, a novel spring clip,

which resiliently attaches to an operating link at one end,

has a spring finger engaging the'metering rod for urgingthe same against the orifice wall. The finger, in turn, is apertured medially to form the operating connection between the link and the rod.

Alternative forms of the present invention are shown in the accompanying drawings, in which;

v Fig. 1 is a vertical elevational view of a carburetor, with parts broken away to show the spring clip connecting the throttle operated link and the metering rod; 1'.

Fig. 2 is a perspective view of the spring clip from thefront. r

Fig. 3 is a similar view from the rear., 7

Figs. 4 and 5 "are views illustrating the manner of ,installation of'the springclip. 7 f g.

- Fig.6 'is aperspective vieweof-a modificationof'the spring clip on an enlarged scale.

Fig. 7 is another view on an'enlarged scae o spring clip shown-in Fig.6. I

Fig. 1 shows a carburetor having a main body portion 1 within which is a mixture conduit containing a throttle mounted on the usual throttle shaft'2. 'Lever 3 fixed to the throttle shaft has a pin 4 received in the slot 5 of reciprocating throttle link or rod actuating member 6. Extending laterally of the link 6 is an extension 7 with a bottom notch 8, perhaps better shown in Fig. 4.

The spring clip 10, which will be described more in detailhereinafter, straddles the extension 7 and engages the notch 8, and forms the connection between extension 7 and a metering rod 12 received within fuel metering orifice 13 as defined by a generally circular wall 14.

Figs. 2 and 3 illustrate the spring clip on an enlarged scale. In the modification shown in Figs. 2 to 5, the main body 15 has a thumb piece 16 and integrally. formed, depending legs 17 and 18 terminating in divergent ends 19 2,936,789 Patented May 17,19 6? ders21 and 22 engage under the lower surface of the notch 8 in the extension 7. The rocking movement during the engagement of the shoulders 21 and 22 tensionsfing'er 24, pressing the olfset portion 26 into engagement with one side of the metering rod 12, which causes it to take up a position against one side of the orifice wall 14.

Figs. 6 and 7 show a modified form of spring clip 30 which has a body portion and spring legs 36 and 37 constructed in the same manner as above described. Likewise, the body portion 35 has a downwardly extending finger 34 apertured at 38 to receive the olfset end of a metering rod 42. The finger 34 has an integrally formed offset portion 39 forked at 40 to engage the metering rod 42.

In operation, with the metering rod 42 in the orifice, aperture 38 is placed upon one leg of. the bent or L-shaped end of the metering rod 42,- and then rotated so that the forked end 40 engages the side of the metering rod. The spring clip'35 is then placed on the extension 7 and pushed downwardly sothat the legs 36 and 37 engagev in the'notch 8.. When so secured, extension 39 is ten-.

sioned, pressing forked end 40 against the side of the metering rod, urging the same against the side of the orificewall14, as shown in Fig; 7.

is contemplated that other modifications will be obvious to those skilled in; the art which come within the scope of.
